WATER-H EATER.

SPECIFICATION forming part of Letters Patent No. 665,197, dated January1, 1901'.

Application filed Apri124, 1900. l Serial No. 14,152. (No model.) i

T0 cir/ZZ whom it may concern:

Be it known that I, HENRY C. ENGLISH, a citizen of the United States,and a resident of Wilmington, Delaware, have invented certainImprovements in Water-Heaters, of which the following is aspecification.

The object of my invention is to so construct a Water-heater as toprovide a large area of heating-surface, to insure the effective actionof the products of combustion and free circulation for the water, and torender unnecessary any elaborate fitting of the parts of the heater.This objectI attain in the manner hereinafter set forth, reference beinghad to the accompanying drawings, in which- Figure l is a verticalsectional view of a water-heater constructed in accordance with myinvention. Fig. 2 is a sectional plan view on the line a a, Fig. 1. Fig.3 is a sectional plan View on the line b b, Fig. 1; and Fig. 4 is a topor plan view, partly broken away to show the interior construction.

The heater has a liaring base 1, containing the ash-pit andv providedwith suitable sup-` ports for the grate 2, which may be of any desiredconstruction, said lower section l having at one side the usual damperedash-pitthe heater comprises a lower hollow casing 4 constituting acold-water chamber, a series of hollow vertical ribs 5, communicatingWithsaid'chamber and projecting inwardly beyond the same, and an upperhollow casing 6, conl. stituting a hot-water chamber and likewisecommunicating with the hollow ribs 5, each water-section of the heaterbeing preferably cast in one piece, so that there are in said heater nojoints which require to be packed,

and consequently no risk of leakage. The portions t of thewater-sections of the heater surround the fire-pot and the lower portion7 of the combustion-chamber, and each of said water-sections receivesits supply of cold water from an appropriate pipe 8, other pipes 9serving to convey the hot water away from the upper portions 6 of eachsection. The

hollow ribs have tapered sides, so as to per- In the inner casing oftheupper portion 6 ofk each water-section of the heater, between the ribs5, are formed slots or openings 10,th rough which the products ofcombustion can escape into a flue contained within a casing 11, mountedupon an external rib on the watersections of the heater and connected atone sideto the smoke-pipe 12, this flue-casing being preferably formedin two right-angled sections with flanges, bolted together lat the`meeting-points, as shown in Fig. 2.

access to any portion of the i'lue is permitted for cleansing or otherpurposes. The valves or dampers also serve as a means of checking thedraftwhen desired.

The upper or hot-water portions 6 of the water-sections of the heatersurround a central opening-14E, and upon said portions 6 is mounted aneck or collar 15, with detachable lid 16, said opening 14 and neck 15constituting the fuel-feed opening ofthe heater, no portion of the sideheating-surface of either of the water-sections of the heater beingsacrificed for the formation of a fuel-feed opening therein.

The cheapness of construction of a waterheater made in accordance withmy invention will be apparent from the fact that it is composed ofsimple castings, which can be bolted or otherwise fitted togetherwithout the necessity of forming any expensive or troublesomeWater-tight joints, and the economical operation of the heater isassured by reason of the large heating-surface presented and thefacilities afforded for direct access yof the products of combustion toall parts of said heating-surface.

Having thus described my invention, I claim and desire to secure byLetters Patent- 1. A water-heater having a water structure comprising alower hollow casing surrounding the fire-pot and containing thecoldwater chamber, an upper hot-water casing, and hollow vertical ribsconnecting said Vchambers and extending inwardly beyond the cold-waterchamber, the extent of projection of the ribs being graduated, thecentral rib of each set having the greatest proj ection and theoutermost ribs of the set having the least projection,substantially asspecified.

2. A water-heater having a water structure comprising a lower hollowcasing surrounding the tirepot and containing the coldwater chamber, anupper hollow casing containing the hot-water chamber and hollow verticalribs connecting the two chambers, and a line structure surrounding andsupported upon the Water structure at the top of the same andcommunicating with the combustion-chamber through openings form ed inthe casing of said Water structure between the projecting hollow ribs ofthe same, substantially as specified.

3. A water-heater comprising a rectangular water structure composed of aseries of iatsided sections each comprising a lower hollow casingcontaining the cold-water chamber, an upper hollow casing containing thehot-water chamber, and a series of hollow vertical ribs connecting thetwo chambers, each section being an integral, j ointless structure,substantially as specified.

4L. A water-heater comprising a rectangular water structure with lowerhollow casing containing the cold-water chamber, an upper hollow casingcontaining the hot-water chamber, and hollow Vertical ribs connectingthe two chambers, in combination with a flue structure surrounding andsupported upon the upper portion of the water structure andcommunicating with the combustion-chamber through openings formed insaid structure, said i'lue structure being rectangular and havingmovable Valves or dampers at the opposite corners whereby access to theinterior of the flue structure is permitted or the draft checked,substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence ol two subscribing witnesses.

HENRY C. ENGLISH.
